ELECTRICAL CONNECTION.

Specification of Letters Patent.

Patented Dec. 3,1918.

Application filed January 21, 1918. Serial No. 213,018.

To all whom it may concern:

Be it known that I, ANsEL F. GURNEY, a citizen of the United States, and a resident of Natick, county of Middlesex, and State of Massachusetts, have invented an 1m:-

provement in Electrical Connections, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in electrical connections, and more particu larly, though not exclusively, to connections for use with a protective flexible armored cable commonly used for protecting electric wire in automobiles and the like. While my invention is of general applicatiomlihave elected to show it as applied to a single wire In the drawings, which show a preferred form of one embodiment of my invention:

Figure 1 is a plan view, showing a preferred form of connector applied to an electric automobile lamp; v

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1; and i Fig. 3 is a transverse section on the line 33 of Fig. 2. Y

The pre erred form of my invention comprises an armored cable 4 havin an expanded portion 5 at one end thereof adapted to rest against a shoulder 6 of an interiorly threaded sleeve '7, the-threads of which engage the threaded portion of a male terminal plug of which preferably bottoms against the expanded end 5 of the cable. The terminal plug 8 is preferably split, as shown, to receive interiorly a conductive terminal means into through the flexible tubing 4 may be secured by any suitable means, though preferably by soldering. To hold the conductive terminal means .10 against movement relative .to the terminal plug 8, I have shown a groove 11 in the conductive terminal means and a cooperating pin 12 in the non-conductive terminal plug 8. To secure the terminal plug 10 of the lamp to the 12, I preferably provide projecting pins or dowels 13 adapted to enter into a slot 14 in the female connector element, thereby providing a bayonet joint connection.

which the, wire passing longitudinal While I have shown and described a preferred form of one embodiment of my invention, it will be understood that major changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from thescope of my invention, which is best defined in the following claims:

. 1. A connector tion, a sleeve providing a shoulder, an armored cable having an expanded end for en-' gagement with said shoulder and a. terminal plug of non-conductive material entered in said sleeve and pressing against the flanged end of said armored cable.

2. A connector comprising, in combina- ,tion, a sleeve for engagement with the end of an armored cable and a split terminal plug entered in said sleeve, said plug having threads. at one end extending across the split therein and engaging threads on the interior of said sleeve.

3. A connector comprising, in combination, of an armored cable and a split terminal plug entered in said sleeve and threaded there-to.

4. connector comprising, in combination, a sleeve, a split terminal plug of noncomprising, in combinaa sleeve for engagement with the end conductive material, and a conductive terminal in said splitv terminal plug removable therefrom when said terminal plug is re- .moved from said sleeve.

5. A connector comprising, in combination, a sleeve, a-split terminal plug of nonconductive material, a conductive terminal in said split terminal plug removable therefrom when said terminal plug is removed from said sleeve, and means opposing longitudinal movement of said conductive terminal in said non-conductive terminal plug.

6. A connector comprising, in combination, a terminalplug of non-conductive material, split longitudinally and provided with a threaded portion; and a cooperating sleeve interiorl threaded for engagement with the threa ed ortion of said terminal plug and effective or holding together the split portions of said terminal plug.

7. A connector comprising, in combination, a terminal plug of non-conductive material, split longitudinally and provided with a threaded portion; an armored cable having an expanded end, and a cooperating sleeve interiorly threaded for engagement with the threaded portion of said terminal a plug and effective for holding together the split portions of said terminal plug While said terminal plug and sleeve engage between them the expanding'portion of said armored cable to maintain the same in operative relation thereto. 10 In testimony whereof, I have signed my name to this specification.
